If you haven't visited the Tumblr site known as Awkward Stock Photos, you're missing out on a daily dose of hilarious photography which embodies the elusive WTF factor.

Occasionally there are NSFW images included, but since they're supposed to be stock photos usable for advertising, videos, etc. they're mostly just ridiculously strange, which makes it hard to figure out what the photographers were thinking when they took these oddball pics.

Take a gander at the site, and if it tickles your funny bone I guarantee you'll be checking back to see what sort of strange new images have been posted.
